Sheep Worms – Sustainable Summer-Autumn Worm Control, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

A summer drenching program for sheep worm control is now recognised as a key cause of drench resistance in Western Australia. However, some small changes can increase the sustainability of pre-emptive control programs. Drenches in summer should always be given to younger, growing sheep (current and previous year’s age groups), whereas adult sheep should be drenched in autumn, or if drenched in summer, some should be left untreated (if drenching at all). Research shows that this reduces the chance of developing drench resistance but still provides effective worm control.

Water Erosion In The South-West Of Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

The averaged annual direct cost of water erosion to dryland farming in Western Australia is estimated to be $10 million, but the costs are much higher in years of severe summer storms.

Water erosion occurs when water flowing over the land surface moves soil particles downslope. Water erosion is a natural process, but is accelerated under agriculture, especially on cropped land. Water erosion causes loss of topsoil, reduced crop yields, damaged infrastructure, weed dispersal, eutrophication (algal blooms) and silting of dams and natural waterways.

Best Practice Marking Of Lambs, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Lambs should be marked between two and 12 weeks of age, with the youngest animal in the mob at least 24 hours old, to ensure the formation of a maternal bond. If lambing extends for more than six weeks, consider having two mulesing/marking sessions.

Lambs should be tail docked using a gas-heated knife or rubber rings and mulesing should only be carried out when necessary.

The provision of pain relief with routine husbandry procedures benefits animal health and welfare and is now a consumer and community expectation. Producers have access to registered products that can relieve pain associated with mulesing, …

Propagation Of Bananas, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

Tissue culture is the best method for propagating bananas. It ensures they are true to type and free from pests and diseases.

Check with Department of Primary Industries and Regional Development quarantine officer before bringing tissue culture material into Western Australia.

However, planting with bits is cheap and guarantees that new diseases are not introduced.

Banana Management In The Ord River Irrigation Area (Oria), Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

The Ord River Irrigation Area (ORIA) is suitable for growing bananas. However, due to the local climate, management is slightly different to other Western Australian growing regions such as Carnarvon.

There are many considerations when planning to establish a banana plantation. A summary of these practices is given below. For more specific information on each practice see the other documents in this series.

Tedera: A Guide To Growing And Utilising This Perennial Pasture Legume, Daniel Real

Animal production and livestock published reports

The commercial release of a new pasture species is a rare and, potentially, important event. In the case of tedera (Bituminaria bituminosa var. albomarginata) we have a novel perennial pasture legume with characteristics which set it apart from anything currently available to growers in Australia or internationally.

Specifically, it is a drought-tolerant, highly productive perennial pasture with the capacity to provide nutritious forage, especially when other feed sources are scarce. Its reaction to drought is in contrast with the few successful perennial legumes available for Mediterranean climatic zones, such as lucerne, as it retains green leaves when water stressed, allowing …

European House Borer Regulations, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Pinewood movement restrictions

To minimise the spread of EHB in Western Australia (WA), restrictions on the movement of pinewood were implemented in 2006, and currently apply to areas where EHB occurs. By restricting the movement of pinewood from EHB infested areas, EHB has been contained to Restricted Movement Zones (RMZs) in the greater Perth metropolitan area.

The restrictions are described in the Agriculture and Related Resources Protection (European House Borer) Regulations 2006.

The regulations allowed for the establishment of quarantine zones, Priority Management Zones (PMZs) and RMZs, and placed restrictions not only on untreated pinewood movement from PMZs and RMZs …

Relief Wells For Water Resources And Managing Salinity And Waterlogging, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Relief wells can provide water resources and help reduce the severity and extent of waterlogging and salinity caused by leaky artesian systems.

A relief well is a 'free flowing' groundwater bore driven by artesian pressure. Such a bore allows groundwater to flow continuously up to the surface by releasing confined pressure stored within the aquifer at depth. This confined artesian pressure is renewed by a percentage of rainfall that infiltrates the soil profile at a higher elevation and recharges aquifers that may be a source of water for a saline seep.

Siphons For Managing Groundwater Discharge And Salinisation In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Siphons are a way of passively moving water from areas of higher hydraulic head to areas of lower hydraulic head, through a pipe. Siphons can be used to lower the watertable under a seepage site if the flow from the siphon (or multiple siphons) is greater than the flow of groundwater to the site. Siphons can reduce surface salt levels at the seepage, but the discharge needs to be to a safe disposal site.

The Department of Primary Industries and Regional Development recommends that siphons are used as part of an integrated water and salinity management program.
